Foreign Office Minister Gillian Keegan was spot on when she told Times Radio this morning that the top rate of tax was a political time bomb left behind by Gordon Brown:

“I always knew that it was going to be a political problem. I mean, let’s be honest, this was a political trap that was set by Gordon Brown in the dying days of his role as PM, right. And I paid the 50% tax. I was in business then. And I remember how devastating it was because actually, it meant you were paying about 65% tax. And there’s something in your mind, which is like, really, you know, only 35% for me? And I’m doing all these hours. I was a business person, then it was set as a political trap…. In theory it [the top rate of tax] should never have been there.”

There is something immoral about the government taking the majority of your income in tax. It is also a disheartening disincentive; reversing this spiteful tax is the correct policy, though this might perhaps be the wrong time. Getting rid of a political tax that was only set up by Gordon Brown when he knew he was likely to be ousted –to hurt the Tories rather than raise revenue – was the right thing to do. Even the IFS’ Paul Johnson thinks in revenue terms “It might plausibly cost nothing at all”. The tax was not about raising revenue – it was about political positioning.

Back in Fife, Brown will be rocking in his chair laughing that his tax booby trap, announced only weeks before he left office, and which was expected to cause problems for his successor David Cameron, has finally exploded in the face of a Tory Chancellor. The fuse wire on Brown’s time bomb turned out to be 12 years long…
